Perturbations in redox status, biochemical indices, and expression of XBP1s and NOX4 in the liver of channa punctatus following exposure to Mancozeb

The study found that Mancozeb exposure leads to increased reactive oxygen species, redox imbalance, and liver biomarker elevation. XBP1s and NOX4 gene expression is also upregulated in response to MZ toxicity, indicating potential for early bio-indicators of endoplasmic reticulum stress.
